项目摘要

2007〜2009年の国際極年において,北極圏の地球環境科学を主題に,各国の大学院生を対象とする国際野外教育学校を企画・実施した.日本とノルウェーの永久凍土研究者で国際的な教授チームを組み,ノルウェー北部のスバルバール諸島を対象に,受講者に対し,(1)調査・観測法を取得させる,(2)2年間で得られた調査・観測データを解析させる,(3)国際学会や国際誌上で公表させる,という三段階の教育を行った.また,調査・観測法だけでなく,北極地域の調査活動に必要なサバイバル・危険回避の技術取得のための訓練も実施した.2年間で,日本,ヨーロッパ,アメリカの国々から,5名の教員,25名の大学院生が参加した.2年目となる2009年度は,8月中・下旬の2週間の期間に,スバルバールのロングイヤーベン地区(内陸)とカップリンネ地区(沿岸)において,セミナー,野外観測,試料採取,室内分析等を実施した.シロクマの出現により,野外活動の一部が制約されたが,充実した指導とデータ取得ができた.共同調査によって得られたデータに基づいて,学生各自がテーマを絞り,北極圏の陸域で起こる永久凍土環境変動の過去・現在・未来の諸側面について考察し,レポートを作成した.とくに,活動層厚の時空的変化,凍土の構成物質,凍土の化学的性質,多角形構造土の分布と内部構造,凍結割れ目の発達プロセスに関して,詳しい成果が得られた.最近の気候の年々変動と長期変動によって活動層厚の変化,永久凍土の部分融解,地形プロセスの年々変動が顕著に起こっており,今後も長期的なモニタリングの継続が必要なことが確認された.成果の一部は2008年7月の国際永久凍土学会で発表した.

From 2007 to 2009, the International Academy of Sciences and the main topic of Earth Environmental Science were held in North Carolina, and university students from various countries were invited to participate in the International School of Field Education program. The permanent soil researcher of Japan, the professor of the International Institute of Agricultural Sciences, the professor of the International Institute of Agriculture, the northern part of the country, the northern part of the country, the recipient, the professor, the professor, the permanent soil researcher, the professor, the professor and the recipient. There are three paragraphs of education. In the North Pole region, the necessary training activities were conducted in the North Polar region, and the technology of emergency avoidance was obtained. in Japan, there were two years of training, five faculty members and 25 university students participated in the annual training program, and in mid-and late August, there were two-year training sessions. In the area (coastal), in the coastal area (coastal), in the field, in the laboratory, etc. A lot of food has been found, and a field operation has been carried out to instruct the train to get it. We have been able to make joint efforts in the field of education, and students have been invited to participate in the study of the permanent soil environment in the north and south of the country. In the past, we have conducted a survey on the environment in the future. The chemical properties of the earth, the chemical properties of the earth, the distribution of the polygonal structure, the internal production of the polygonal structure, the transformation of time and space, the formation of the earth, the chemical properties of the soil, the chemical properties of the earth, the polygonal structure, the distribution of the polygonal structure, and the results of the experiment are satisfactory. Recently, long-term weather activities have been intensified, the permanent soil has been partially melted, and the terrain has been triggered by long-term weather events. In the future, it is necessary to make sure that long-term weather events occur. The results of the International permanent soil Society of China in July 2008.
